Antidepressant use in Canada has increased, with over half of prescriptions potentially for major depression. However, many individuals taking antidepressants do not have a current major depressive episode, indicating other uses.

Area of Science:

  • Psychiatry
  • Public Health
  • Epidemiology

Background:

  • Antidepressant utilization serves as a key indicator for effective major depression treatment.
  • Characterizing antidepressant use patterns is crucial for understanding mental healthcare in Canada.

Purpose of the Study:

  • To analyze antidepressant utilization in Canada.
  • To investigate the association between antidepressant use and sociodemographic factors, depression history, and other indications.

Main Methods:

  • Utilized data from the Canadian Community Health Survey (CCHS) Cycle 1.2, a nationally representative mental health survey.
  • Included diagnostic instruments for past-year and lifetime major depressive episodes and recorded past-year antidepressant use in 36,984 participants.

Main Results:

  • Overall, 5.8% of Canadians reported antidepressant use, exceeding the 4.8% prevalence of past-year major depressive episodes.
  • Among individuals with a past-year major depressive episode, 40.4% used antidepressants, estimated to be over 50% after treatment outcome adjustments.
  • Only 33.1% of antidepressant users had a past-year major depressive episode; over 60% had conditions like migraine, fibromyalgia, anxiety, or past depression.

Conclusions:

  • Antidepressant use in Canada has significantly increased since the early 1990s.
  • A substantial proportion of antidepressant prescriptions are for conditions other than current major depression.
